It's fundamental to their freshness that they are packed in manner that will give them a long shelf life -- if they're allowed to oxidize, flavor compounds and aromatic properties will slowly degrade. To preserve freshness, Lavazza immediately packs their beans directly after roasting in high-barrier multilayer material that guarantees perfect vacuum packaging. The roasting process, however, allows for the release of carbon dioxide and this represents 90% of the gas that forms inside of the package. To keep the bag from bursting, one-way valves are sealed into the package to allow the gas to escape without letting any air in. This one-way valve system guarantees vacuum packaging, even though the bag may sometimes be "puffy" and not compact.
